Isaiah 56:6-8

6I will also bless foreigners who decide to serve me. They must be faithful to me as my servants. They must respect the rules for the Sabbath day and keep it special. They must always obey my covenant.

7Then I will bring them to my holy mountain. I will make them happy in my house, where people pray to me. I will accept their burnt offerings and sacrifices, when they offer them to me on my altar. People will call my temple, “A house where people from all nations may pray.” ’

8The Almighty Lord is the one who brings together all the Israelite people who are in exile. He says, ‘I will continue to bring more people to join with them.’
